- I picked this TV up from a condo straight out of the '80s a few weeks back. Like Miami Vice '80s! It was awesome. The TV did work for a few minutes when I got it home, but the picture quickly began to distort just before the vertical collapsed. I unplugged it and let it sit for a few weeks until I was ready to make the repair video. At that time, it would no longer get a picture or sound. I could here it get power and the sleep lamp on the front would come on, but I never got snow or static. I resolved that issue by replacing several capacitors, but once it began to power up again, the vertical collapse issue appeared to be intermittent. This failure was traced to the Vertical Deflection area of the board. Although I never saw exactly where the cold solder was, after reflowing the solder in that area, the failure was resolved. Now the tv functions and looks great!
I do not recommend you working on your own tv without an understanding of the potential risks involved.
All you need now is the matching TV stand for the KV-2670R.
Beautiful television! If you haven’t already, you might wanna go back in and check/resolder the Horz drive transformer connections. Also check around the STR regulator area, incredible find man!
you have been very missed sir!
I really appreciate it! Good to be back.
We call the cold joint a dry joint , love to of seen where on the pcb it was
Coming from tiktok you just saved the meal time 😂😂
Good to have you back! I have the kv-2665, basically the non-remote version of this set. Thanks for posting!
Awesome! Such a cool set. Thank you!
You love to see it. I love seeing you bring this beauty back to life.
This was great, love your IG, hope to see you post back here more often.
Excellent work on a gorgeous set! Thanks for the video, darlin'!
Seen your Tiktok and was really interested for the full repair. Very cool.
You are amazing 👏👏👏 it’s incredible how you repaired this TV . I love your channel and content 👏
Hey Matt, I'm a big fan of the early Betamax players. I was a teenager in 1975. Graduated high school. I have bought a 7200 Betamax the first stand alone one that I wanted back in the day. But It cost over a thousand dollars back them. I have it now with the clock timer. I am just wanting a couple of the original blank tape to go with it. K30 or K60. I seen you had a big box of them. Would I be able to purchase one or two from you. I can't find them anywhere. It would make my collection complete. Please, Please consider. I will pay top dollar for them. Thanks, Your video's are awesome...Gary
Yup, your reel brought me here as well. Right up my alley. Subbed.
Very Cool, brings me back to my childhood. Thank you for everything you do! 📽🎥🎬🎃
Inside the tv is so clean there is no dust in it, it has been cleaned before the video taken
Just discovered your channel. Love the content! Keep it up! 😄
Awesome video 👍
Saw your ad on Instagram, the algorithm sometimes gets it perfectly right
Great work, thanks for the video!
Yes new video!!! I saw one in Craigslist!!
Wonderful.
Such a great concept for a UA-cam channel
Excellent video. Thanks for your patience and honest method in fault finding. Ive worked as an electronic engineer for over 20 years with mostly modern digital equipment but ive got a real affinity and interest in old electronics like CRT TVs and 8-16 bit games consoles. Ive recently bought a working mega drive gen 1 and a mitsubishi CP-1627BM just to clean up and maybe upgrade with some new capacitors etc if needed. Any solid advise for me starting out this hobby in regards to equipment spare parts and sourcing repair manuals for old electronics? I live in the UK.
Nice one mate...
I’m in NC and your house looks like it could be in my neighborhood. I have a smaller atomic ranch and I love orange too. You’ll have to reach out when you get settled in.

Nice work! Can you go into more detail regarding the equipment you use and how to use it properly? I’ve got a 90’s set I’m about to start replacing caps on.
It’s always good to get a refresher on discharging the high voltage, too. I’m still working up the courage to do it myself for the first time.
40 years old. wow
Would’ve been nice if you could’ve shown where the the cold solder was at
I cannot believe how clean this was inside, whose condo was this, Howard Hughes??
It was business television. I think it's cool.

Given how many were bad and how relatively few there are, I'd just replace them all, that thing is beautiful, but opening it up to repair it all the time with that long thin neck and giant neck board would make me nervous. Never seen the inside of a CRT TV so clean.
Do you know how to remove small scratches or a graze on the glass of a crt TVs?
What brand is that ESR meter?
Hello Matt, I love your content. I was hoping that you could help me with some issues that I have with my Video Cassette Recorder. If it's no trouble for you.
I have the JVC HR-2200U Video Cassette Recorder, and it’s fully functional, I can watch tapes with no problems. The only issue is when I want to record with it. I’m using a Panasonic WV-3060 Color Video Camera, which works because I can see an image through the viewfinder and when I press the camera’s trigger switch the recording starts and the tape advance. The REC and PLAY indicators are lighting, so I assume that the recording is taking place. But when I rewatch the tape to see what I recorded, nothing appears. I have no image that has been recorded or sound. Do you know what may be the problem and how to fix it? I appreciate a lot your answer and help!
Mod RGB?
Hello! I have a question concerning your last video. Were you able to find the schematics and/or manual and fix it? Wishing you the best of luck!
That project got pushed to the side as other things came up. I plan to get back to it eventually. I do have the schematics!
@@vintagevideobasement Sounds good. Is it possible to fix or replace a bad green electron gun?
Cool tv,I keep a floor console in the basement so the kids can play duck hunt and I have it on a antenna so I can watch the rockford files and Quency M.E. . Most people don't get but I like watching the old shows and movies on a tube,especially the annual holiday stuff like Friday the 13 and Halloween every year
Caps aren't all that pricy. Why not just replace them all?
Fully recapping a crt is time consuming, I have done it on my Toshiba 27AF44, I didn't see major inprovement from replacing the problematic caps to the full recap
you skipped the cold solder part. So am not impressed.
I never actually saw the cold solder. I reflowed the vertical deflection part of the board, and the intermittent failure was resolved. I forgot to film that part too. It’s a hassle to set up the camera in multiple locations and film yourself while you just want to get the job done. I’ll work to show more details in the future. Thanks for the comment.
